AppncationieaAprn16,1583. (No modem To all whom, it may concern.:

Be it known that I, MARK A. PENNEY, a citizen of the United States, residing in Des Moines, in the county of Polk and State of Iowa, have invented a new and useful- .Im-

provement in Barb-Wire-FenceMachines, of which the following is a specication.

This invention relates to machines for the manufacture of barb-wire fencing. I have endeavored in devising it to produce a simple, strong, and inexpensive machine, capable of being run at a uniform high rate of speed.

The nature of the invention will be fully comprehended from the following description; and it consists in the novel construction and combinations set forth. p

In the accompanying drawings,.forming a part of this description, Figure l is a plan of my improved machine. Fig. 2 is a side 'elevation, with the frame partially broken away to show the various movements. Figs. 3,4, and 5 are transverse sections on the line 3 3, line 44, and line 5 5, respectively, of Fig. 1. Fig. 6 is a vertical longitudinal section through the barb-severing devices. Figs. 7 and 8 are horizontal sections upon lines 7 7 and 8 8, respectively, of Fig. 6. Fig. 9 is a plan of the lower knife. Fig. 9a is a bottom view of the cap covering the guide upon the lower knife. Fig. l() is1a bottom longitudinal section of the coiling-cylinder, and Fig. 1l shows the rack and pinion for actuating the barb-feed rolls.

The wire passes into the machine from two coils supported on bracket A, bolted to the main frame A, and' enters first between the grooved feedrrolls B B and B B', which are geared together by gears B2 Baupon the same `shafts, b b', therewith, and intermittent motion isimparted to said rolls by the pins c upon the wheel C, and the cam C fastened on the main shaft D. This cam C is provided with a rim, continuous except at one poiiit, where its ends are turned out laterally in opposite directions, and it revolves in the spaces between the pins c, as clearly illustrated, moving the pin-wheel one space at each revolution. The main shaft is actuated by bevelgears D D2, shaft D3, and belt-pulley D4. 5o That one of the wires which is fed by rolls B B issues from thence to the hollow spindle E,

supported on bearings e e, and to which a conv tinuous rotation is `given by pinion e', intermediate gear, ez, and large gear e3 on the main shaft. Said .intermediate wheel is supported upon a bracket, 6*.

'Upon the forward end of the spindle E is a sleeve, E, keyed to the spindle by the feather E2, so as to rotatetherewith, but fitted thereon with sufficient freedom to allow it to re- 6o ciprocate to a limited extent independently of the spindle, though it also reciprocates therewith. The feather Il2 is dovetailed in the sleeve, and it or a pin upon it operates to coil the barbs on the wire. A spring, Ff, presses the spindle forward to the extent permitted by the contact of the'collar E4 with the standard e, and when thus pressed forward with the coil- 'ing-feather in advance, as in Fig. 10, the parts are in position to seize and coil the barb. 7o After the coiling, the sleeve is retracted by the sliding bar. E5, which carries a fork or clutch, e5, upon its forward end, fitting into the annular groove e6 upon the sleeve, the power for this function being carried to said bar from the grooved cam EG on the main shaft through the medium of the roller or stud e7, crank-arm e8, shaft' or spindle e9, confined in the hollow upright ew, the lateral arm of the bell-crank lever c, and 'pin e. The cam E6 is sofashioned that it retains the coiler in the retracted position long enough for the Vbarb to be severed and the fence-wire to be fed forward a barb-space. The spindle does notretract with the sleeve until the latter strikes the shoulder 8 5 ew'upon the former, thus having a more limited reciprocation than does the sleeve. This differential reciprocation of the two parts is provided in order that the spindle may continue to serve asa sort of guide or abutment to the end of the barb after the withdrawing movement of the coiling-pin has commenced, and insures the projection of the barb-point at right angles to the main wire. W'hen the time arrives for coiling the next barb, the sliding bar is actuated in a forward direction by the same mechanism, and carries the sleeve with it into position for that operation, while at the same time the spring returns the spindie, and both sleeve and spindle are4 left to Ico rotate in this position until the barb is coiled. The spring also holds the spindle in the'advanced position during the eoiling. rIhebarbwire is fed in during the advance of the fencewires by the feed-rolls F F, the shafts f of which are geared together by gears F F. The lower shaft, f, has also a loose gear, F2, with iiangefz, carrying a pawl, f3, engaging with a ratchet-wheel, j, keyed fast to the saine shaft. By means of these, said feed-rolls receive periodical motion from the rack F",which is operated by the bell-crank F, actuated by the cani F5 upon the main shaft, said crank having upon one arm a suitable stud or roller fitting into the groove of said cams, and being connected to the rack by the other arm. The lower knife, G, for cutting offl the barb-wire is fitted and confined in a groove in the sliding head G by the cap g, and is adjusted vcrtieally therein by means of the screw g. A guide, g2, for the barb-wire is placed directly over the knife, but not so as to cover the cut ting-edge thereof. It is a narrow piece of iiat metal, the inner end acting to direct the barb and the outer end being bent down at right angles, as shown. lt is adjusted by the screw gfx and held by the cap yf, the under side of the cap being grooved at m to admit the barbwire. The head G is actuated by the side groove-cani, G2, upon the main shaft, and is first raised thereby to cut off the barb, then lowered to let the barb pass, then raised enough to allow the guide g2 to guide the next barb while it enters and is being coiled, and is held in this latter position until again raised to cut. It is connected to the cam by the bar g5 carrying the stud-roller g". The gibs gl gl are eniployed to take up wear. The upper knife, H, is fitted in a head,H, and held therein by a cap, h. Said head is oscillated upon the center of motion h by means of the horizontally-sliding bar h2, to which it is connected bya pin, h, and said bar is actuated by the forward arm of the bell-crank lever e" (the same lever by which the coiling device is reciprocated) through the medium of the pin h". rlhe lower knife-head slides in and the upper head is centered upon the bracket H2, and the former is confined therein by guides h, and the latteris confined upon its center of motion by the cap h, the screw hl, and the washer' h. After the barb is coiled, the upper knife is swung to a position directly over the lower knife, which then rises and severs the barb, after which both knives are withdrawn, as already described, to give room for the ceiling-head as it advances to coil the succeeding barb. Just before entering the hollow journal I of the twister, the wire upon which the barbs are placed is j oined by the companion wire passing through feedrolls B B, and the two are then twisted together. The twister is actuated by the gears I and I2 from the main shaft, and is supported by the pedestal l, as shown. The shaft-s of the main feed-rolls and barb-feed rolls are supported in bearings K and L, respectively. The former are placed upon the upright rods K', the bearings of the bottoni rolls being secured upon said rods by set-screws k, while the top rolls are forced downward with sufficient power to move the wires by the screw k and spring k2. On the barb-feed rolls the pressure-screw Z is placed directly over the bearing next the rolls, as illustrated.
